Ballplayer's Toolkit
By Emmett Tolis
NOTES: Input Batting Average as a decimal
To get a Per Game Efficiency rating, divide the score by games played
How It Works:
The Ballplayer Offensive Value Rating (OVR) is a combined metric running off 8 commonly counted statistics to attempt to boil down a ballplayers offensive season to a single statistic. The values are private, but heavy emphasis is placed on the ballplayer’s ability to Reach base, and hit home runs. Stringing singles together is difficult for a team to do these days, so the player’s ability to tally XBH’s is emphasized. Singles and batting average are influential, but in modern baseball, slugging is a requirement. This is normalized by detraction on K’s, which are by nature less productive than fly balls and ground balls(that do not result in GIDP) with runners on base, so we don’t see names like Joey Gallo, or Adam Dunn at the top of the list.
In practice, the best names peak out toward the 100 mark, for example
-
Vladimir Guerrero JR’s 2021: 99.7
-
Mike Trout’s 2019 MVP season:93.1
-
Miguel Cabrera’s 2012 Triple Crown Season: 109.4
While Very good Offensive seasons Accumulate around the 80-85 point
-
Shohei Ohtani’s 2021 Season: 83.0
-
Robinson Cano’s 2012 Season 82.9
